*Notes:
Mets by SCCA
Most common benign mandibular tumor
Ameloblastoma
Most common cystic lesion of the mandible
Radicular cyst (referring to the root)
Globular cyst at the root or apex of a devitalized tooth
This is a well circumscribed radiolucent lesion that develops around the crown of an impacted or unerupted tooth
Dentigerous cyst (follicular cyst)
Cyst containing keratin
Unilocular or multilocular cyst with sharply demarcated borders
Adjacent to the third molar
Rapidly growing
Odontogenic keratocyst
Unilocular or multilocular radiolucent cyst containing variable amounts of calcified material
Calcified odontogenic cyst
Occurs in the maxilla 70% of cases
Cyst that continues to grow after a tooth is extracted
Residual cyst
Cyst that develops from the tooth primordia in the third molar location
Indistinguishable from a residua cyst
Primordial cyst
Cyst the can extend to the alveolar ridge without bone disruption
Traumatic bone cyst
